The primary objective in removal of waste is to improve the Order Production Cycle where the time from _________________ to the time of receipt of…

A foundational concept of Lean, famously articulated by Taiichi Ohno, is compressing the lead time across the end-to-end value stream. The Order Production Cycle (or Order-to-Cash cycle) measures the elapsed time from the exact moment a customer order is received to the point payment is collected. Removing non-value-added wastes along this pathway streamlines the process, shortens lead times, and improves cash flow.

A. Shift start represents an operational working boundary, not the customer-driven order trigger for the value stream.

B. Product development covers initial product design and engineering, which occurs prior to the execution of customer order fulfillment.

D. New fiscal year is an accounting timeline and does not reflect operational order-to-cash lead times.
